- Size type estimation of international freight transport for container sea transportation
There are many kinds of containers for transporting goods, ranging from small folding containers for transporting household articles to 40 feet standard containers, as well as aviation containers. This is only an introduction to the size and type of international freight containers that are common in sea transportation.
Container size
20 feet in the cabinet: size 5.69 m X2.13 m X2.18 M / picking gross weight is generally 17.5 tons / volume 24-26 cubic meters
40 feet in the cabinet: size 11.8 m X2.13 m X2.18 M / picking gross weight is generally 22 tons / Volume 54 cubic meters
40 high cabinets: size 11.8 m X2.13 m X2.72 M / picking gross weight is generally 22 tons / volume 68 cubic meters
45 feet in the cabinet: size 13.58 m X2.34 m X2.71 M / picking gross weight is generally 29 tons / Volume 86 cubic meters
20 feet of freezer: size 5.42 m X2.26 m X2.24 M / picking gross weight is generally 17 tons / Volume 26 cubic meters
40 feet of freezer: size 11.20 m X2.24 m X2.18 M / picking gross weight is generally 22 tons / Volume 54 cubic meters
40 high freezer: size 11.62 m X2.29 m X2.50 M / picking gross weight is generally 22 tons / Volume 67 cubic meters

Classification by use
The containers in the container are generally divided into:
(1) the general dry cargo container (Dry Cargo Container), also known as a grocery container, is used to transport the groceries without controlling the temperature. It has a wide range of use. According to statistics in 1983, 85% of the 3 million containers in the world were grocery containers, about 2 million 540 thousand. The container is usually closed, with a box door at one end or side. This kind of container is usually used for shipping cultural goods, chemical products, electronic machinery, arts and crafts, medicine, daily necessities, textiles and instrument parts. This is the most commonly used container. All kinds of solid bulk goods, particles or powder unshaped goods that are not affected by the temperature change can be shipped by such containers.
(2) heat preservation containers (Keep Constant Temperature Container) they are for transporting goods that need to be refrigerated or insulated. All container walls are insulated from materials with low thermal conductivity, which can be divided into three types:
(1) refrigerated container (Reefer Container) it is a thermal insulation container, which is mainly used to transport frozen food and can maintain the fixed temperature. It is specially designed for transporting food such as fish, meat, fresh fruit, vegetables and so on. Current international refrigerated containers used are basically divided into two types: one is called mechanical refrigerated containers with a freezer container; another box is not only insulated freezer structure, which is provided with the air inlet and the air outlet in the container on the end wall, boxes installed in the cabin, refrigeration equipment from the supply of air ship this is called, clutch type refrigerated containers (known as external type or clip type refrigerated container).
2. Insulated container. It is a container which has enough insulation structure for carrying fruits, vegetables and other goods to prevent excessive temperature rise and maintain freshness. It is usually used as refrigerant for ice, and the heat preservation time is about 72 hours.
Ventilation container (VentilatedContainer) is a container for carrying fruits, vegetables and other products that do not need refrigeration. The container with ventilation holes on the end wall and sidewall can also be used as a grocery container if the vent is closed.
(3) tank container (TankContainer) it is a container for liquid goods such as liquor, oil (such as plant and plant oil), liquid food and chemicals. It can also ship dangerous goods of other liquids. The container has a single tank and multiple tanks, and the four corners of the tank are made up of a support and a bracing frame. Because of the greater strength of the side wall, the relatively dense bulk cargo, such as malt and chemicals, is generally loaded, while the latter is used to load grain with relatively small relative density. The loader at the top of the bulk container shall have a good watertight cover for intrusion of rain water into the box.
(4) pedestaled container (Platform basedContainer) it is not the top of the box and the side wall, end wall even removed and only a bottom plate and four corner of the container. This container can carry out loading and unloading operations from around about and above, suitable for loading and loading grew up, such as heavy machinery, steel, steel, wood, steel etc.. There is no water tightness in the frame type container. The goods that are afraid of water and wet can not be shipped or cover the shipment with canvas.
(5) the platform container (PlatformContainer) is a special structure container that is simplified on the platform container and only reserved for the floor. The length and width of the platform. With the international standard container at the bottom of the same size, can use the same fasteners and lifting device and other containers. The use of the container broke the concept that the container had to have a certain volume.
(6) open top container (Open TopContainer) this is a container without rigid top box, but by folding or folding roof support canvas, plastic cloth or plastic cloth canopy, other components and similar general container. This container is suitable for large and heavy loading of goods, such as steel and wood, especially like glass and other brittle America from the top into the box is not easy to be damaged by the crane, but also facilitate the fixed in the box.
(7) car container (CarContainer) it is a small container transport car, which is characterized in the simple bottom is provided with a steel frame, usually without walls (including end wall and side wall). The containers are divided into two types, single layer and double layer. Because the height of the car is 1.35 meters to 1.45 meters, such as the standard container of 8 feet (2; 438 meters), the volume is more than 2/5. As a result, there are double containers. The double deck container has two kinds of height: one is 10.5 feet (3.2 meters), and one is 2 times as high as 8.5 feet. As a result, car containers are generally not international standard containers.
(8) animal container (PenContainerorLiveStockContainer) which is a shipment of chicken, ducks and geese live poultry and cattle, horses, sheep, pigs and other livestock live container. In order to shelter the sun, the top of the plywood box side and end use dew cover, aluminum wire made of windows, in order to have good ventilation. The side wall is equipped with a cleaning mouth and a drainage port, and is equipped with a sliding door that moves up and down, so that the garbage can be cleaned out. There is also a feeding mouth. Animal containers are usually loaded on board on board because the air on the deck is easy to clean and take care of.
(9) clothing container (GarmentContainer) container has the characteristics that there are many cross bars on the upper side beam, and there are several buckles, nylon buckles or ropes on each bar. The clothes are directly hung on the buckle or rope by hook on the hanger. This clothing loading method is a non package transportation. It not only saves the cost of packaging materials and packaging, but also reduces manual labor and improves the transport quality of clothing.
Practical skills! A small square for estimating the size of the packing
Many people will ask how to accurately estimate the size of the packing. Actually, the method is very simple. After knowing this small method, as a salesman of foreign trade company, you don't have to rush to worry about waiting for a factory for a long time, but also haven't given it to it for a long time.
Take a coil notebook for example, if you know the size of the book is A5 size, 250gsm White Card Cover, 70gsm offset paper * 60 sheets.
At this time, you only know the information, there is no physical in hand, even the size and weight of a single product do not know, how to calculate it?
First, determine the individual weight of the product
The size of A5 is about 21cm*14.8cm
GSM is a gram / square meter.
A single weight of about =0.21*0.148*70*60+0.21*0.148*250*2+15=160g
(according to the weight of the paper weight and the number of sheets, the weight of the inner page and the cover are calculated respectively, and then the weight of a coil is estimated).
Two. Determine the volume of each box again
For example, the outside weight of the box is not more than 15KGS.
We can according to the weight of about 12kgs to count, 12000/160=75 (possibly many times customers are in love from the packaging, each containing 72 of the more reasonable, of course, if you do not want to provide in the box, can also direct the 48 according to a carton, the specific needs of the reference characteristics of their own products to you)
Three. Determine the size of the carton
In most cases, we can know the size of the product, in this case, the length and width of the notebook all know, but do not know the thickness, it is only the first estimate, such as coils of the 60 sheets, we according to the thickness of about 6mm, the diameter of the coil will be higher than some. When we consider the thickness, packaging is generally two of the two to put it, we can according to the single thickness of about 7mm to count.
If it is 12 an inner box, the inner box is the size of the box.
Product size: 21cm x 14.8cm x 0.7cm
Inner box size: +1 x +1 x *12+1
=:22cm x 16cm x 9.5cm
After the product is heap up, the size of the inner box is generally 1cm
Outer box size: (in this case, there will be 6 inner boxes in an outer box, if it is calculated by 3 layers and 2 rows).
Inner box size: 22cm x 16cm x 9.5cm
Outer box size: +2 x *2+2 x *3+3
=:24cm x 34cm x 31.5cm
That is to say, the outer box size is 34 x 24cm x 31.5cm
The inner box after the heap, generally outside the box size is the length and width of the 2cm high pressure 3cm
Gross weight: 160*72g+2kg inner box outer box weight = about 13.5kgs
Remarks：
1) this method is estimated, the size and weight of a loaded out will have the difference, so only recommended when the conditions are not allowed to try the case.
2) some irregularly shaped products, when calculating the size of the inner box, should pay attention to how to put the product into play. For example, 2 products may be considered to save space for inserting, so the size of the product should be accounted for when the 2 products are put together.
3) if you know the size and weight of a single product, then jump over the first and look at it.
